Judith Mendez <jm@ti.com> says:
The following patch series includes a MMC tuning algorithm
fix according to the following published paper [0].
This seris also includes fixes for OTAP/ITAP delay values
in j721e_4bit_sdhci_set_ios_post and for HS400 mode.
For DDR52 mode, also set ENDLL=1 and call am654_sdhci_setup_dll()
instead of am654_sdhci_setup_delay_chain() according to
device datasheet[1].

At HS400 mode the ITAPDLY value is that from High Speed mode
which is incorrect and may cause boot failures.
The ITAPDLY for HS400 speed mode should be the same as ITAPDLY
as HS200 timing after tuning is executed. Add the functionality
to save ITAPDLY from HS200 tuning and save as HS400 ITAPDLY.

According to the device datasheet [0], ENDLL=1 for
DDR52 mode, so call am654_sdhci_setup_dll() and write
itapdly after since we do not carry out tuning.

Set itap_del_ena if ITAPDLY is found in DT or if the tuning
algorithm was executed and found the optimal ITAPDLY. Add the
functionality to save ITAPDLYENA that can be referenced later
by storing the bit in array itap_del_ena[].

Currently the sdhci_am654 driver only supports one tuning
algorithm which should be used only when DLL is enabled. The
ITAPDLY is selected from the largest passing window and the
buffer is viewed as a circular buffer.
The new tuning algorithm should be used when the delay chain
is enabled; the ITAPDLY is selected from the largest passing
window and the buffer is not viewed as a circular buffer.
This implementation is based off of the following paper: [1].
Also add support for multiple failing windows.

Caleb Connolly <caleb.connolly@linaro.org> says:
This is a subset of [1]. With more platform maintainers switching to
OF_UPSTREAM I didn't want to get in the way (it has also proven more
difficult than I hoped to remove only the fully compatible header
files).
This series removes only the dt-bindings headers which contain generic
data like GPIO flags, input event codes, etc.
It then implements support for building all DTBs for a vendor with
OF_UPSTREAM_BUILD_VENDOR. This removes the need to maintain a set list
of DTBs that can be built by U-Boot and opens up the possibility of new
boards becoming supported "by default" just by landing their DT
upstream.
[1]: https://lore.kernel.org/u-boot/20240321-b4-upstream-dt-headers-v2-0-1eac0df875fe@linaro.org
|
|
This adjusts OF_UPSTREAM to behave more like the kernel by allowing for
all the devicetree files for a given vendor to be compiled. This is
useful for Qualcomm in particular as most boards are supported by a
single U-Boot build just provided with a different DT.

MD Danish Anwar <danishanwar@ti.com> says:
The series introduces device tree and config changes and AM65x
to enable ICSSG driver. The series also enables SPL_LOAD_FIT_APPLY_OVERLAY
for AM65x in order to load overlay over spl.
The ICSSG2 node is added in device tree overlay so that it remains in
sync with linux kernel.
This series has been tested on AM65x SR2.0, and the ICSSG interface is
able to ping / dhcp and boot kernel using tftp in uboot.
The users need to set env variables fw_storage_interface, fw_dev_part,
fw_ubi_mtdpart, fw_ubi_volume to indicate which storage medium and
partition they want to use to load firmware files from. By default the env
fw_storage_interface=mmc and fw_dev_part=1:2 but users can modify these
envs as per their requirements.
|
|
When ICSSG driver is enabled (CONFIG_TI_ICSSG_PRUETH=y) set
storage_interface and fw_dev_part env variables.
These variables need be set appropriately in order to load differnet
ICSSG firmwares needed for ICSSG driver. By default the storage
interface is mmc and the partition is 1:2. User can modify this based on
their needs.

To workaround an issue in AM642 we reset the SoC in early boot. For that
we first probed the sysreset driver by calling uclass_get_device(). The
ti-sci sysreset driver is now probed during the ti-sci firmware probe.
Update this call to probe the firmware driver which will then probe
the sysreset driver allowing do_reset() to again function as expected.

In Linux, we allow sleep moci to be turned off when the carrier board
supports it and the system is in suspend. In U-Boot, however, we want
the sleep moci to be always on. So we use a gpio hog and disable the
regulator. This change is necessary because we switched to upstream
device tree files with commit c07bba7a2c7e ("verdin-am62: move verdin
am62 to OF_UPSTREAM"). A recent upstream patch removes the gpio hog from
the Linux device tree, so we need to add it to the u-boot dtsi. The
following patch will remove the gpio hog from the Linux device tree:
https://lore.kernel.org/linux-devicetree/20240301084901.16656-1-eichest@gmail.com/
The U-Boot patch can be applied without it and will not break the build.

In commit 51aaaf5e7975 ("board: toradex: imx: Remove not needed env variables")
the empty definition of fdt_fixup variable was removed, however this was
still referenced from the boot command leading to boot failures:
## Error: \"fdt_fixup\" not defined`
Fix this by removing "run fdt_fixup" from the boot command and instead
enable CONFIG_OF_ENV_SETUP in the defconfig that would achieve the same
but in a more robust way (it works fine even if the variable is not
defined).
